Abstract:
The Australian Centre for Geomechanics (ACG) has developed a simple, but effective, regional seismic monitoring system that has a number of strategic and tactical applications for monitoring seismicity in mines. From a strategic perspective, installation of a regional seismic sensor is a means of evaluating the severity of a local seismicity problem. This can help decide if a full-blown in-mine microseismic monitoring system is required. From a tactical perspective, a regional seismic sensor can provide a series of operational benefits, including: blast vibration monitoring, blast diagnostics monitoring, identifying events within mine blasts, monitoring of near-mine seismic events, and as backup for an in-mine microseismic system. The versatility of stand-alone regional seismic sensors make them useful tools for mines that do not have a seismic monitoring system, as well as for mines with established in-mine seismic systems.
